MODULAR ENERGY STORAGE SYSTEM WITH TEMPERATURE CONTROL

A temperature-controlled energy-storage (ES) system of a materials-handling vehicle comprises a plurality of ES modules, each ES module comprising a plurality of ES units. The ES modules may be secured within a substantially vertical stack. The ES modules may comprise temperature control (TC) elements that may be secured over respective ES units. The TC elements may comprise TC couplings configured to connect the TC elements to a heat exchange system in parallel. A separator may be disposed between lateral ends of the ES units and the TC couplings.
